Adam bought a box of fruit that weighed 6 and 3/8 kilograms. If he bought a second box that weighed 7 and 2/5 kilograms, what is the combined weight of both boxes?

answer: it is 8

step-by-step explanation:

you know why its 8

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

you should go to the second answerthey explain it very well, give me a like

first the equation needs to be simplified. so the equation would now look like:   52-24+11

then you multiply.

and when you multiply, you will get the answer of 39.
